The Isetta is an Italian-designed microcar built under licence in a number of different countries. Produced in the post-World War II years, a time when cheap short-distance transportation was most needed, it became one of the most successful and influential city cars ever created. Because of its egg shape and bubble-like windows, it became known as a bubble car, a name later given to other similar vehicles.(WikiPedia)YouTube
